Mucinex? Egg white lube?


Has anyone heard of taking mucinex for helping with fertility. My hubbys SA came back abnormal. They say his semen is too thick and it’s hard for the swimmers to make it up stream. I recently heard of the men and woman being able to take mucinex and it helps thin it out. Has anyone tried this? Also last night I was reading and a woman said she used egg whites as lube. Has anyone heard of that?
